Conversion of geared DC motor into stepper motor using switching delay time signals

Abstract In solar tracking system, general stepper motor is used to control the stepwise movement and low speed of panel in vertical motion. Degree rotation directly proportional (stepping method) motor. But it cumbersome process hold a at particular position depending on sun’s using cost motors. So, geared DC implemented into for low-speed applications Stepping Method ( GDCSM ). per step identified Step angle switching delay time signal (A) microcontroller. Speed controlled by passing fixed interval between pulses where have width. Controlling (D) Combining effect signals A D represents Method. method resembles controlling 10RPM & 30RPM motors operated 10V power supply. Microcontroller ATmega 328P with Performance analyzed terms Relative slip degree error revolution RE $$_\mathrm{{S}}$$ S ) acceptable slippage tolerance under open loop condition. Change consuming voltage $$\varDelta$$ Δ during another parameter which maintain constant actual total count revolutions GDCSM. At 40 ms , has 120 steps . 25 55 controllable up 2RPM when its or value less than equal 1%. If − 0.4%, then behaves like suitable system movement. experimentally showed better result commercial available 28BYJ-48 STP-43d1027-01.
